.To all whom it may concern.-' I

' Be it known that 'I, MILTON B. SMYTHE, a citizen of the United States, residing at. Holton, in the county of Jackson and State of Kansas, have invented a new and useful Vehicle-Tire, of which the following is a sp ecification. I

This invention relates generally to, vehicletires, andv more particularly to tires of that class em loyed u on automobiles.

The e ject of t e invention isto dispense with the ordinary rubber pneumatic tire and g in lieu thereof to provide a novel form of tire which shall possess the same 'resilienc asa pneumatic tire but be devoid of its disa vantages, such as the danger ofbeing punctured, mutilated, or requiring frequent repairs. i A further object is in a novel manner positively to prevent skiddin and. to increase 2 the tractive properties of t e tire.

, .With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination ofparts 2 5 of a cushion vehicle-tire, as will be hereinafter fully described and claimed.

In the accompanying drawings, for part of this specification, and, in whi" characters of reference indic'a ing parts, Figure I is a View- I portion of a vehicletire';'ciinst cordance with the presentinvent I I 4 the same assembled with hewheel r I 2 isa view in transverse sectionflthroug he '1' 3 5 tire'shown in Fig;f1. I Fi .3 i-is' .a transver "-1 'tional view through a s iglit -rnodifi of tire.

I 9 is an edge view of a ortion of a slightly modified form of shieltfor tread, exhibiting, more particularly,

means for connectingthei ends thereof. Fig. I'D-is a view in'plan of the shield shown in "$517.9. 1

= 'eferringito the drawings at Fi s/1,

2, and 4 thereof, 1 designates the rim, and 2 the spokes, of a vehicle-wheel. The rimis, by preference, made of metal and is provided with the usual channel 3, inwhich the ordinary tire fits, and a supplemental channel 4 for a purpose that will presently appear.

The tire 5 is constructed'of an endless coiled spring which, as shown in Fig. 2, is approximately heart-shaped in cross-section in order to provide teats or tire-holding elements 6,

and seats or shield holding elements 7. The teats enga e the supplemental channeli, and thus positively hold the tire against lateral movement relatively to the rim and are firmly-locked in place by a keeper 8, which consists of a bar of metal that rests in the groove formed by the teats and is held thereby J-bolts 9, the hooks of which, as shown in Fig; 2, embrace'the keeper and the shanks of which project through the rim and carry nuts 10. These bolts or locking elements are to be s aced at an desired distance apart and w il be tho'roug effective for the urpose designed. f The s 'eld or tread to w 'ch refe h s be en'made consists of a plu- 11, each provided on its outer c with 'a ground-engaging element 12 and asjinne face with a rib 13 to engage the seats; 7, as; clearly shown in Fig. 2. 'As lio'wn .4, the traction element 12 is V- ;shaped, an this form of element will be fleinplfoyedon the rear tire in order to secure ithe highest; possible traction, while the like ele ents-1a onj'the links 15 of the tread of .thB:fTQ I1t Wh6el will be straight and extend inally of the links, as shown in Fig. means for connecting the links j'iFigji i consists of hooks 16, ro- 'ded-at o'ri'terminal of the link and o ces ded at the other terminal, while in of tread shown in Figs. 5 and 6 ection between the links is secured by ngs 18 that engage alined orifices 19 in the J "terminals of the links. Of course it will be; understood that, if preferred, the links 15 may be provided with hooks and orifices similar to those shown in Fig.4, and, asthis will,

ICO

be obvious, detailed illustration of such arrangementis deemed'unnecessary.

'In assembling the tread with the tire the individual coils thereof will oe compressed,

in order to permit the hooks on one terminal of the tread to enga e with the orifices of the other terminal t ereof, and when the parts are'thus combined the will be positively held against accidents separation in tire, and thereby prevent any rocking movement relatively thereto.

In the form of the invention shown in Fig. 3 the tire 21 has its outer face circular, and a plied to this surface isa rubber shield 22. w 'ch may be held combined with the tire in any preferred manner. The inner surface of the tire is provided with teats 6, similar to those shown in Figs. 1 and 2, that are held within the supplemental channel 4 of the tire by a keeper 8 andd-bolts 9 in the manner described. Instead of securing the terminals of the tread in the manner described the two end links 23 and 24 (shown in detail in Fig. 7) may have their opposed ends pro vided with outstanding o'riiiced lugs 25 and 26, the orifice in one being right-hand threaded and that in the other left-hand threaded and the two orifices being en aged by a right and left hand threaded boIt 27, adapted to be turned by a suitable implement, thus to place the tread under requisite tension. The bolt will be preferably made of brass in order to prevent it from becoming rust-locked.

In the form of the invention shown in Figs. 8, 9, and 10 the links 28 of the shield may be of the same construction shown in Figs. 4 and 6, the main difference being that the links are connected by open rings 29, one being disposed at each end of a link and be tween its sides and engaging an orifice 30 therein. Each of the terminal links is rovided with a dOWHWftI'd-GXtQIldlHg ori ced toe 31, through which projects a right and left hand threaded bolt 32, having between its ends a polygonal abutment 33 to be engaged by a sultable wrench to effect turning of the bolt. The terminals of the bolt carry nuts 34, the semispherical inner faces of which are mounted and bear against the outer faces of the toes, and thereby reduce friction between these arts to a minlmum,

, as the nuts will yield re atively to the toes in the use of the tire. In order to bridge the space between the two toes, thus to maintain t 'e continuityof the tread, there is a bridge piece or plate 35 provided, which is, by preference, formed integral with one of the terminal links and has its free end dis osed over the other. This bridge-piece is 0 substantially the same hei ht as the ground-engaging element12 an will therefore exert tragtive folrce in ulse. d b d em 0 n t e 0 en rings, as escri e the hield as h whole ivill be rendered more flexible, may be more cheaply constructed,

\ and will be thoroughly eflective for the purposes designed.

The improvements herein defined while any of its disadvantages.

I claim 1. The combinationivith a rim provided with a non-resilient channel, of a tire composed of convolutions provided with alining teats to engage the channel, and means for securing the teats within the channel.

2. The combination with a rim provided with a channel, of a tire composed of convolutions having teats to engagethe channel, a keeper engaging the inner walls of the teats, bolts having means to engage the keeper, and nuts carried by the bolt.

3. The combination with a rim, of a tire composed of convolutions, the outer faces of which are provided with seats, and. a tread consisting of connected elements having parts to engage the seats.

4. .The combination with a rim provided with a channel, of a tire composed of convolutions the inner portions of which are provided with teats to engage the channel and the outer portions of which are provided with seats, means for securing the teats within the channel, and a sectional tread having the inner face of its members provided with ribs to engage the seats and their outer faces provided with traction devices.

5. The combination with a'rim provided with a channel, of a tire composed of convolutions the inner portions of which. are provided with teats to enga e the channel and the outer portions of whic are provided with seats, means for securing the teats within the channel, and a sectional tread having the inner faces of its members provided with ribs to engage the seats and their outer faces provided with V-shapcd traction devices.

6. The combination with a rim, of a tire com osedof eonvolutions, the outer faces of whic are provided with seats, a tread consisting of connected elements having parts to engage the/seat, and means for connecting the terminals of the tread and for holding the same undertension.

- 7. The combination with a rim, of a tire com osed of convolutions, the outer faces of tion device for connecting the terminals of the tread and for holding the same under tension.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
